Vom 16. bis 31. August 2026 fand in Jülich die QuantenAkademie der Bildung & Begabung gemeinnützige GmbH (Tochter des Stifterverbands für die Deutsche Wissenschaft) statt. Diese richtete sich an begabte Schülerinnen und Schüler der Oberstufe mit dem Ziel, sie intellektuell durch Inhalte jenseits des regulären Schulstoffs herauszufordern, den Austausch mit Gleichgesinnten zu fördern und Orientierung für ihre Zukunft zu geben.

Grafik (first published in npj Quantum Information (2026)): Various light-based simulator approaches corresponding to different approximation methods. From right to left, the experimental complexity of the simulator increases as additional operations must be performed.
A recent study revealed how different methods for simulating molecular vibrations - important for understanding how molecules absorb and emit light – map to various light-based simulators with varying complexity. Jan-Lucas Eickmann and colleagues conducted the work in collaboration with HQS Quantum Simulations as part of the PhoQuant project. The research was led by Dr. Michael Stefszky and Prof. Christine Silberhorn at the Institute of Photonic…

Mesoscopic Quantum Optics
In everyday life, events happen in a fixed sequence: one thing happens before another. In quantum physics, however, nature can behave in surprising ways. One such phenomenon is indefinite causal order, where the order of two events is not fixed but exists in a quantum superposition. Rather than occurring in one sequence or the other, both orders can effectively happen at the same time until the system is measured. This unusual feature has…

Integrated Quantum Optics
Researchers at the Institute of Photonic Quantum Systems (PhoQS) have published a paper combining experimental and theoretical physics expertise from two research groups: the Integrated Quantum Optics group, led by Christine Silberhorn, and the Theoretical Quantum Science group, led by Jan Sperling. In this collaboration, Jonas Lammers, Laura Ares, and co-authors present a new type of photonic processor for quantum information processing.Unlike…
What exactly are photonic quantum systems, and how can light particles and quantum physics be used to transmit data? Scientists from the Institute and 21 school pupils explored this question on 2 July 2026 as part of a one-day programme on offer at the UPB Summer University , organised centrally by the empowerMINT team. The aim of the programme, ‘Photonics-based quantum systems – an interdisciplinary exploration of light particles’, was to…

Three research groups at the Institute for Photonic Quantum Systems and the Physics Departement of Paderborn University – Theory of Functional Photonic Structures (Prof. Dr Stefan Schumacher), Ultrafast Nanophotonics (Prof. Dr Thomas Zentgraf) and Theoretical Quantum Science (Prof. Dr Jan Sperling) – have made progress in the field of modern photonics in their latest work. In two publications, the researchers investigated how light can be…
On Tuesday, 12 May 2026, the Collaborative Research Centre TRR 358, the Institute of Mathematics and the Institute for Photonic Quantum Systems at Paderborn University invited interested schoolgirls to the new PhoQS Lab. The event was aimed at schoolgirls in grades 9 to 12 who wanted to find out more about Mathematics, Physics and their application in current research. A total of 12 schoolgirls from a large catchment area took part - from…
